1.0 APPLICATION

1.1 PURPOSE: The Sayfl ine Synthetic Rope Horizontal Lifeline System
is designed for use as an anchoring means for one or two persons.
Use the Sayfl ine Horizontal Lifeline System where horizontal
mobility and fall protection are required.

1.2 LIMITATIONS: The following limits apply to the installation and
use of the Sayfl ine Synthetic Rope Horizontal Lifeline System.
Other limitations may apply:

IMPORTANT: OSHA regulations state that horizontal lifelines
shall be installed and used under the supervision of a qualifi ed
person (see below for defi nition) as part of a complete personal
fall arrest system that maintains a safety factor of at least two.

QUALIFIED PERSON: An individual with a recognized degree or
professional certifi cate, and extensive knowledge and experience
in the subject fi eld, who is capable of design, analysis,
evaluation, and specifi cation in the subject work, project, or
product. Refer to OSHA 1910.66, 1926.32, and 1926.502.

A. HORIZONTAL LIFELINE SPAN: The maximum span distance

is 100 feet. The span length must be reduced when clearance
is limited. See section 3.2 for clearance information.

B. ANCHORAGES: The Sayfline horizontal lifeline must be

installed on anchorages that meet the requirements specified
in section 2.4.

C. SYSTEM CAPACITY: The maximum capacity of the Sayfline

horizontal lifeline is two persons. The maximum weight of each
person, including tools and clothing, is 310 lbs. (141kg).

D. CONNECTING SUBSYSTEM: Each person’s connecting

subsystem must limit fall arrest forces to 900 lbs. (4kN) or
less. See section 2.5.

E. FREE FALL: Rig and use the personal fall arrest system

such that the maximum potential free fall does not exceed
Government regulatory and subsystem manufacturer’s
requirements. See section 3.0 and subsystem manufacturer’s
Instructions for more information.

F. SWING FALLS: See Figure

2. Swing falls occur when
the anchorage point is not
directly overhead. The force
of striking an object in a
swing fall may cause serious
injury or death. Minimize
swing falls by working as
directly below the anchorage
point as possible. Do not
permit a swing fall if injury
could occur. Swing falls will
significantly increase the
clearance required when a
self retracting lifeline or other
variable length connecting
subsystem is used. If a swing
fall situation exists in your
application, contact DBI-SALA
before proceeding.

G. FALL CLEARANCE: There must be sufficient clearance below

the worker to arrest a fall before striking the lower level or
obstruction. See section 3.2 for required clearance information.

H. BODY SUPPORT: A full body harness must be used with the

Synthetic Rope Horizontal Lifeline System.

I. ENVIRONMENTAL HAZARDS: Use of this equipment in areas

with environmental hazards may require additional precautions
to reduce the possibility of injury to the user or damage to the
equipment. Hazards may include, but are not limited to; heat,
chemicals, corrosive environments, high voltage power lines,
gases, moving machinery, and sharp edges. Contact DBI–
SALA if you have questions about using this equipment where
environmental hazards exist.

J. TRAINING: This equipment must be installed and used by

persons trained in its correct application and use. See section 4.0.

1.3 APPLICABLE STANDARDS: Refer to national standards, including
ANSI Z359.1, local, state, and federal (OSHA 1910.66 and

1926.502) requirements for more information on personal fall
arrest systems and associated components. In Canada, see the
Z259 group of CSA standards.

2.0 SYSTEM REQUIREMENTS

2.1 PERSONAL FALL ARREST SYSTEM COMPONENTS: The
Sayfl ine horizontal lifeline must be used with DBI-SALA approved
components and subsystems. Non-approved components may
be incompatible, and could affect the safety and reliability of the
complete system. Personal fall arrest components used with this
system must meet all applicable OSHA and ANSI requirements. A
full body harness must be used with this system.

2.2 PERSONAL FALL ARREST SYSTEM CONNECTORS: Connectors
used to attach to the attachment O-ring on the horizontal lifeline
(hooks, carabiners, D-rings) must support at least 5,000 lbs.
Connectors and attachment elements must be compatible in
size, shape, and strength. Non-compatible connectors may
unintentionally disengage (roll-out). Do not use non-locking
connectors with this system.

2.3 ANCHORAGE CONNECTORS: Connectors used to attach the
horizontal lifeline to end anchors must be compatible with the
connection point. The connection must be positive; and, with
connecting elements, capable of sustaining a 5,000 lbs. (22.2kN)
load without failure.

2.4 STRUCTURE LOAD: Structural anchorage points must be rigid,
and capable of supporting at least 3,600 lbs. (16kN) along the axis
of the horizontal lifeline. Anchorages must also support at least
3,600 lbs. (16kN) applied in all potential directions of fall arrest that
are perpendicular to the axis of the horizontal lifeline. See Figure 3.

WARNING: Anchorages must be rigid. Large deformations of
the anchorage will affect system performance, and may increase
the required fall clearance below the system, which could result
in serious injury or death.

2.5 CONNECTING SUBSYSTEM: The connecting subsystem is the
portion of the personal fall arrest system that is used to connect
between the horizontal lifeline subsystem and harness fall arrest
attachment element. The connecting subsystem must limit forces
applied to the horizontal lifeline to 900 lbs. (4kN) or less.

3.0 OPERATION AND USE

WARNING: Do not alter or intentionally misuse this equipment. Consult

DBI-SALA when using this equipment in combination with components or
subsystems other than those described in this manual. Some subsystem
and component combinations may interfere with the operation of this
equipment. Use caution when using this equipment around moving
machinery, electrical hazards, chemical hazards, and sharp edges.

WARNING: Consult your doctor if there is reason to doubt your
fi tness to absorb the impact from a fall arrest. Age and fi tness can
affect your ability to withstand fall arrest forces. Pregnant women and
minors must not use this system.

3.1 BEFORE EACH USE inspect this equipment according to section

5.0. Do not use this equipment if inspection reveals an unsafe or
defective condition. Plan your use of the fall protection system
prior to exposing workers to dangerous situations. Consider all
factors affecting your safety before using this system.

A. Read and understand all manufacturer’s instructions for each

component of the personal fall arrest system. All DBI-SALA
harnesses and connecting subsystems are supplied with separate
user instructions. Keep all instructions for future reference.

B.

Review sections 1.0 and 2.0 to ensure system limitations and

other requirements have been adhered to. Review applicable
information regarding system clearance criteria, and ensure
changes have not been made to the system installation (i.e.
length) or occurred at the job site that could affect the required
fall clearance. Do not use the system if changes are required.

3.2 SYSTEM INSTALLATION: Figure 1 shows a typical Sayfl ine
horizontal lifeline installation. When using an energy absorbing
lanyard to connect to the system, the end anchorages must be
located at a height which will limit the free fall to 6 feet (1.8m).
When using a self retracting lifeline (SRL) to connect to the
system, the end anchorages must be located above the user. The
SRL, when fully retracted, must be above the harness attachment
level. The horizontal lifeline system should be positioned at a
level that will minimize free fall while allowing ease of use. The
horizontal lifeline should be positioned near the work location to
minimize swing fall hazards. The connecting subsystem length
should be kept as short as possible to reduce the potential free
fall and required clearance distance. Both anchorages must
be installed at approximately the same elevation, so that the
horizontal lifeline system is not sloped more than 5°.

Step 1. Determine the locations of the end anchorages and

evaluate their strengths in accordance with section 2.4.
Determine the span length and evaluate the required
clearance using Figures 4, 5, or 6 and Tables 1, 2 or 3.
